suo'rIoN CLEANING DEVICE... a

1B whom may concem:

Beit; known that we, WALTER. S. CHns'roN and THOMAS A. MCINTYRE, Jr., citizens of the United States, and residents of the borough of Manhattan, city, c011nty, and State of New York, have invented certain new and useful Improvements :-in Suction Cleaning Dev ces, of' whichthe following is a specificat on, accompanied by drawings.

1 This invention relates to vacuum or suction cleaning devices, more especially to portable devices for cleaning purposes, and

' the objects of the invention are to improve upon such devices, simplify'the parts, and make the operationmore certain and efli- To,these ends the invention consists of a device which is shown in its preferred forms inth'e' accompanying. drawings, in which- Q e11 is aside elevationpartly in loninal section, of a device embodying the Invention; Fig. 2is a detail en'delevation of one member of the device, and Fig. 3-is a side elevation partly broken away of a mgdification.

Til-Referring to the drawings and more partiillarly to Fig. 1, the device comprises a suitable suction-pump A, a collecting cham a 1 her B communicating with thepump casing,

and a collecting nozzle C, the suction end of the: device being adapted to rest upon a supporting surface, as for instance, the floor to be cleaned, while the opposite end of the de-- .vice' is supported 'by suitable mechanism suction to the nozzle.

adapted to be rocked, thereby bodily moving the entirecleaning device back and forth, at the same time operating the pump to apply In this instance the pum A'comprises the casing D, which may be '0 cylindrical form, having the heads E and F suitably secured thereto, whishwithin the casing is provideda bellows, which may conveniently be a double-acting bellows having the piston connected to the diaphragm H. Said diaphragm H is connected in any suitable manner to the heads 13 and F as by means of the cords or wires J. The piston or plunger G is provided with the piston rod K passin through the tubular sleeve L 'hi-ch is s 'tably secured to the head E and forms a. tight jointwith the piston rod withutthe, interposition ofa stufling box. We ave found that this construction operates :atisfactorily and well without the inconvenience attendant upon the use of a stufling ox; The head'F is provided with the inlet.

l port 0 and the collecting chamber B is suitably secured to said head F, so that communication is afforded between said chamber and the pump. 'vided for the inlet port OJ The head F is also providedwith an outlet port P provided i with the outlet valve 6. A passageway Q, is

provided in ;the head F preferably communicating with the inlet port 0 and any suitable hose or tubing R connects the pas-.

sageway Q, with the inlet port 8 in the head E. A suitable inlet valve 0 controls the inlet ,port S. The head Ejis also provided with the outlet port T having the outlet valved. In the operation of the pump,

movement of the piston G toward the head F, forces air out of the outlet port P and sucks air from the collecting chamber B through the passageway Q, tubing R and lnlet port S in the head E. Movement of An inlet valve a is pro-' the piston G toward the head E. sucks air through the inlet port 0 in the head F and v forces air out from the outletport T in the head The collecting chamber or casing B as shown is provided with the removable head 6 to which is suitably secured the bag f, the inner end of which is clamped by 'a suitable clamp g. The bag f may be fastened to the head e as by means of the cord or wire 72., .and the head is held upon the casing J3 as. by means of the bolts j and thumb screws k. The head 6 is preferably prof and also extending outwardly beyond the head. The collecting nozzle C is preferably remo'vably connected to the tube 0 by any .suitable means, in this instance the end of vided with the tube 0 extending into the bag the nozzle tube C being thrust over the end of the tube 0 and held by friction.

The devices for operating the cleaner are constructed to support the operating end of' along the surface to be cleaned. The entire cleaning device may also be moved along the surface to be cleaned and in the form ofthe apparatus shown in Fig. 1,,but one operator is required. We have'found that tog-- gle acting devices maybe devlsed and suit-=5 "ably connected to the cleaning device insuch manner that the pump may be operated and the collecting nozzle C reciprocated by one operating or rocking support U which forms one member of the toggle. The other member of the toggle is formed by a supporting rod V suitably secured to thevpump casing D as by means of the bands 9. The other end of the rod or toggle member V is pivoted to the toggle member U at the point 1*. Both members may be conveniently provided with apertures s and t in order to afford provision for adjusting said members at different heights and angles, in order to vary the stroke of the apparatus. I

One end of the rocking member U is preferably provided with the foot-rest or stirrup W adapted to rest upon the floor or supporting surface or the surface to be cleaned. The stirrup W may also be provided with a roller X or other suitable device upon which the foot of the operator rests, as indicated in the drawing. The end W of the rocking member or support U is thus temporarily held stationary, while the upper end of the member U having the handle Y is grasped by the operator and moved back and forth or reciprocated with the stirrup as a pivot, thus transmitting motion'through the toggle member V, to the cleaning device.-

The piston rod K is also pivoted to the member U as by means of the short link Z pivoted atv to the piston rod K and pivoted at w to the member U. The member U and the link-Z are both provided with apertures m and y. to afford provision for adjustment between the parts. By the reciprocation of the member-U, with the lower end W held stationary, motion is transmitted through the link Z and piston rod K to the piston G which in turn operates the bellows to continually apply suction to the nozzle C. As the operators hand, indicated in the drawing, is moved backward in the direction of the arrow 2, the angle between the members U and V is decreased and the distance be.- tween the head E and the member U is de creased, thus forcing the piston G forward toward the head F. The forward movement of the upper end Y oftlie member U produces the opposite movement of the piston G. The operation of the toggle acting devices thus produces relative movement between the piston G and the pump casing.

In the modification shown in Fig. 3-, the

device is constructed as illustrated in Fig. 1, except that the collecting chamber B=is-pro-' vided with a head 2 having a bracket 3 carrying a roller 4 adapted to travel along a supporting surface, which may be the surface to be cleaned, as for instance, the floor of a. room. The head 2 is provided with a flexible hose or connection 5 preferably supported by'the bracket "6 having the ring 7. A suitable collecting nozzle C'is adapted to be connected to the hose 5,'so

- operative connections that the cleaning device may be Operated upon the floor or other surface whilethe nozzle connected to the hose-5 may be passed over chairs, sofas or hangings or other ob:

jects to be cleaned. The operation of the device shownin Fig. 3 is similarto that shown in Fig. l, and in both cases the suc-' tion .end of the device is adapted to be reciprocated upon a supporting surface, while the other end of the cleaning device is elevated and connected to a toggle acting mechanism.

Obviously the cleaning device may bepushed along the floor or other supporting surface to any desired position and the device may be operated for cleaning purposes in any position in which it may conveniently be'placed. A double-actingpump or bellows has ferred form of the invention, but we are not to be understood as limiting the'device to a double-acting suction pump, and the pump itself may be of any suitable con- L struction.
